Claims. (Cl. 118-401) This invention relates to the treatment of yarns with liquids, and more particularly to improved apparatus for the treatment of yarns of natural laments as well as those of artificial or synthetic filaments, such as nylon and the like.

In the treatment of yarns of various types it is frequently desired to apply a liquid thereto for moistening, -for applying size, or for other purposes. The quantity of liquid supplied must be adequate but not excessive.

In our application for Letters Patent for Treatment of Yarns, led June 19, 1952, Serial No. 294,332, the treatment of yarn with liquids is shown for which the apparatus of the present invention is particularly suitable.

It is the principal object of the present invention to provide improved apparatus for the treatment of yarn and more particularly for the continuous application of liquid thereto While the yarn is in motion.

It is a further object of the present invention to provide improved apparatus for the application of liquid to yarn in Which the quantity of liquid delivered to yarn may be varied as desired.

It is a further object of the present invention to provide apparatus for the application of liquid to yarn which includes a container for the liquid, an applicator within the container and extending therefrom, and a cover for the container which is capable of use for adjusting the delivery capacity of the applicator.

It is a further object of the present invention to provide apparatus for applying liquid to yarns in which an applicator is provided with a suitable yadjusting structure for determining the quantity yof the liquid delivered to the yarn.

Other objects and advantageous features of the invention will be apparent from the specification and claims.

The nature and characteristic features of the invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is a vertical central sectional view, enlarged, of a preferred form of apparatus in accordance with the present invention;

Fig. 2 is a vertical sectional view taken approximately on the line 2-7-2 of Fig. 1;

Fig. 3 is a top plan View of the liquid container with the cover plate and applicator in position;

Fig. 4 is a horizontal sectional vieW taken approximately on the line 4 4 of Fig. 1; and

Fig. 5 is a horizontal sectional View taken approximately on the line 5-5 of Fig. 1.

jIt should, of course, be understood that the 2 description and drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed Without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the drawings, in which a preferred embodiment of the invention' is illustrated, a liquid container I0 is illustrated with a hollow cylindrical upper body portion II terminating lat a rim I2. The lower portion of the container I0 has positioning ribs IIa formed therein, and has a bottom opening I3 for the supply of liquid. The interior of the container is thus in communication with a tube I4 preferably formed integral with the container I 0 and disposed perpendicularly to the axis of the container body. The container I0 and tube I4 may be made of any preferred material, such as glass or molded synthetic plastic material resistant to the liquid delivered thereto, but the container I0 is preferably of transparent material so that the level of the liquid therein may be determined by visual inspection.

The tube I4 is adapted to be connected by tubing I4a in series with other tubes of other containers, and with a suitable source of liquid supply (not shown) which is preferably also of a character to maintain a uniform level of liquid Within the containers I0.

The rim I2 of the container I0 is preferably provided with alined recesses I5 for the reception of opposed extensions I6 formed on a cover plate I1.

The cover plate I'I is provided with a diametrically disposed slot I 8 therethrough with the termini I9 spaced at a predetermined distance for purposes to be explained. It will be noted, that the extensions I6 when positioned in the recesses I5 prevent turning of the cover plate I1 as Well as reducing access of dust and the like to the interior of the container I 0.

The applicator 20, as shown more particularly in Figs. l and 2, preferably comprises a piece of round Wire of any preferred size, wire of a diameter of 0.07 inch having been found satisfactory.

The applicator 20 included a pair of outer side legs 2I connected at the bottom by a resilient loop 22, which permits of springing these legs 2l slightly by engagement with the termini I9 for purposes of adjustment. The legs 2| 'at the ltop are connected by loops 23 to inner legs 24.

'converging relation so that they are closer as their lower termini than at their place of connection to the loops 23, but are capable of being brought to a substantially parallel or converging relation to adjust the gap therebetween.

The maximum exterior dimensions of the applicator 2Q, transversely considered and as seen in Figs. 1 and 3, are slightly greater thanthe distance between the ends i9 of the slot I8 so that by selection of a particular length of slot I8 the spacing between the inner legs 24 may be xed as desired. 1f desired, the legs 24 may be preset at the desired spacing and employed with a slot I8 of a length which does not engage the legs 2| at its termini I3. The applicator 20, if bottomed in the container l0, may thus be set for a particular spacing of the legs 24..

In use, as will be seen in Fig. l, the applicator 2l! has the lower portions of the legs 2l and loop 22 therebetween and the lower portions of the inner legs 24 immersed in the liquid in the container lil and the upper portions of the inner and outer legs 2 l and 24 extend beyond the cover plate I1 for the reception, between the inner legs 24, of the yarn to which the liquid is to be applied.

The container lll with the applicator 20 positioned therein may be disposed, as desired or required for a particular installation, with the longitudinal axis of the container l vertical, in which case the yarn may be advanced horizontally or at an angle such that it does not touch the cover plate il. If desired, also, the container l2 may be disposed with its longitudinal axis inclined where vertical or inclined advance of the yarn is desired.

Liquid from the container IB will rise by capillarity between and along the inner legs 24 and be available for application to the yarn passing between the legs 2li. As the liquid is withdrawn by the advancing yarn, additional liquid will rise as needed by capillary action for continuous feed.

The quantity of liquid available for application to the yarn may be varied as desired by the positioning of the applicator 25 in the cover plate ll which determines the spacing of the legs 24 and the size of the capillary gap therebetween. The quantity of liquid delivered to the yarn may also be varied by adjustment of the level of the liquid in the container l El.

We claim:

1. In apparatus for applying liquid to yarn, a liquid container, an applicator extending into the container and outwardly therebeyond for passage therethrough of the yarn, said applicator being made from wire and having a pair of outer legs connected by a loop at the lower ends thereof and a pair of closely spaced inner legs for the reception of the yarn connected at the upper ends to the outer legs by loops of smaller size than said rst mentioned loop.
